Conditional instructions

Conditional instructions should be easy to understand. If more than one condition requires the same sequence of actions, list each condition separateiy. [Pg.72]

Figure 5 19. Conditional instructions. In the correct example, the conditions are listed for ease of reading rather than hidden in a string of text. Figure 5 19. Conditional instructions. In the correct example, the conditions are listed for ease of reading rather than hidden in a string of text.
Are conditional instructions easy to understand If an action must meet more than two requirements, are the requirements listed ... [Pg.129]

Operating procedures often contain conditional instructions, i.e., the person following the instructions will be required to take different courses of action depending on the current operating conditions. [Pg.354]

Absolute concentrations are, however, often difficult to establish due to the lack of information on extinction coefficients and due to different adsorption probabilities under the prevailing conditions. Instructive examples for research along these lines are the observation of Cu-Zn interactions in working methanol synthesis catalysts [28] and of coexistence of metal and ionic Ru sites in alumina-supported Ru catalysts for partial oxidation of methane [29]. [Pg.186]

Instructions and procedures shall be developed for normal operations of the spent fuel storage facility, anticipated operational occurrences and design basis accident conditions. Instructions and procedures should be prepared so that each action can be readily performed in the proper sequence by the designated responsible person. Responsibilities for approval of any required deviations from procedures for operational reasons should be clearly defined. [Pg.20]

For records on weather maps, meteoroiogists customariiy correct barometer readings to sea ievei, and some barometers may be caiibrated accordingiy. Such instruments are not suitabie for iaboratory use where true pressure under standard conditions is required. Scaie corrections shouid be specified in the maker s instructions with the instrument, and are aiso indicated by the iack of correspondence between a gauge mark usuaiiy piaced exactiy 76.2 cm from the zero point and the 76.2-cm scaie graduation. [Pg.145]

A plot of equation 13.18, shown in figure 13.10, is instructive for defining conditions under which the rate of an enzymatic reaction can be used for the quantitative analysis of enzymes and substrates. Eor high substrate concentrations, where [S] Kjq, equation 13.18 simplifies to... [Pg.637]

Under modern condition the ordinary layman...has neither the opportunity nor the capacity to inspect or to determine the fitness of an automobile for use he must rely on the manufacturer who has control of its construction, and to some degree on the dealer who, to the limited extent called for by the manufacturer s instructions, inspects and services it before delivery. In such a marketing milieu his remedies and those of persons who properly claim through him should not depend "upon the intricacies of the law of sales. The obligation of the manufacturer should not be based alone on privity of contract. It should rest, as was once said,... [Pg.98]

Flexible batch. Both the formula and the processing instructions can change from batch to batch. Emulsion polymerization reactors are a good example of a flexible batch facility. The recipe for each produc t must detail Both the raw materials required and how conditions within the reac tor must be sequenced in order to make the desired product. [Pg.752]

Tanks, Vessels, ana Equipment Flat, curved, and irregular surfaces such as tanks, vessels, boilers, and breechings are normally insulated with flat blocks, beveled lags, curved segments, blankets, or spray-apphed insulation. Since no general procedure can apply to all materials and conditions, it is important that manufacturers specifications and instructions be followed for specific insulation applications. [Pg.1103]

It is instructive to collect the important relations here for comparison to the jump conditions derived in Section 2.4. When the bead parameters are replaced with the properties of particle and shock velocities, force and internal energy, the relations can be written as... [Pg.14]

Whilst the conductivity of these polymers is generally somewhat inferior to that of metals (for example, the electrical conductivity of polyacetylenes has reached more than 400 000 S/cm compared to values for copper of about 600 000 S/cm), when comparisons are made on the basis of equal mass the situation may be reversed. Unfortunately, most of the polymers also display other disadvantages such as improcessability, poor mechanical strength, poor stability under exposure to common environmental conditions, particularly at elevated temperatures, poor storage stability leading to a loss in conductivity and poor stability in the presence of electrolytes. In spite of the involvement of a number of important companies (e.g. Allied, BASF, IBM and Rohm and Haas) commercial development has been slow however, some uses have begun to emerge. It is therefore instructive to review briefly the potential for these materials. [Pg.888]

Typical division of responsibilities in a road transport operation are shown in Figure 15.1. Producers transporting their own products need to establish a system to ensure that all necessary information and instructions are provided for safe handling under all foreseeable conditions. This will require ... [Pg.461]

You need an improvement system that causes improvement opportunities to be identified. Relying on chance encounters will not create the conditions needed for continuous improvement. The data that needs to be analyzed will be generated by a particular process and this process governed by particular documented procedures. By having already placed instructions in these procedures for certain data to be transmitted to your data analysts, you can cause opportunities to be identified. Other opportunities that are less dependent on product or process data may arise from the audit process and particular projects such as benchmarking, customer and supplier surveys. [Pg.112]

The standard requires controlled conditions to include documented procedures defining the manner of production, installation, and servicing where the absence of such instructions would adversely affect quality. The supplementary requirements also require job instructions for all employees having responsibilities for the operation of processes and for these job instructions to be accessible for use at the work station without disruption to the job. [Pg.352]

Since the Fries rearrangement is a equilibrium reaction, the reverse reaction may be used preparatively under appropriate experimental conditions. An instructive example, which shows how the regioselectivity depends on the reaction temperature, is the rearrangement of m-cresyl acetate 8. At high temperatures the ortho-product 9 is formed, while below 100°C the para-derivative 10 is formed ... [Pg.128]

This reaction also represents an example of the intramolecular Heck reaction, a variant that has gained some importance in recent years. Another instructive example of the potential of this reaction for the construction of ring systems has been reported by de Meijere and coworkers, taking advantage of a sequence of four consecutive intramolecular Heck reactions. The bromodiene-yne 18 reacts in a sequence of domino reactions within 3 d at 80 °C under Heck conditions to give the tetracyclic product 19 in 74% yield ... [Pg.157]

The effect of a particular element on the odour of its compound seems also to lend support to the residual affinity theory, for it is only the elements which possess residual affinity in certain of their compounds, which function as osmophores. Oxygen, nitrogen, sulphur, phosphorous, halogens, arsenic, antimony, bismuth, etc., whose valencies vary under certain conditions are powerfully osmophoric whereas carbon, hydrogen, and many others which have a constant valency are practically non-osmophoric, and it is very instructive to note that the element is osmophoric when it is not employing its full number of valencies and therefore has free affinity. [Pg.37]
